Free and Open Source: The Inside Scoop on FME and FOSS

“Open source tools play well with others.” Paul Ramsey, PostGIS founder, talks Open Source at the FME International User Conference 2014.

As a software developer, coding something that’s already been designed, implemented, and optimized is a pretty gigantic waste of time.

Open source libraries help developers avoid re-inventing wheels. At this year’s FME UC, PostGIS founder Paul Ramsey took the stage to talk about the awesomeness that is Open Source. He explained how it’s important that developers use available knowledge—and FME devs understand this, adding value by building useful functionality on top of open source libraries.h

Safe Software proudly supports the Free and Open Source Software (FOSS) community and regularly sponsors the North American FOSS4G conferences. FME uses many FOSS libraries, and when the devs here at Safe aren’t playing soccer or LEGO or a game of oversized Jenga, they’re working hard to make these libraries more accessible.

Our use of these libraries is a friendly two-way street. A two-way Yellow Brick Road, if you will. FOSS adds value to FME’s advanced data transformation and automation capabilities, while our contributions to these technologies have included funding, coding, testing, and bug fixes. Here are ten such libraries.

10 FOSS Libraries that FME Uses and Contributes to

1. Mapnik

Mapnik is a toolkit that renders raster and vector data into beautiful cartographic maps. FME’s Mapnik transformer lets users leverage Mapnik’s capabilities with any of the 325+ data formats FME supports. With Mapnik and FME, you can also create Web Map Tiling Services, make a map out of your face, map yer way to buried treasure arr matey!, and other such highly critical tasks. FME’s intuitive graphical interface makes it easy for any user to benefit from this complex library.

2. SpatiaLite

SpatiaLite extends SQLite into a simple Spatial DBMS. FME’s SpatiaLite Reader / Writer allows users to connect this format with hundreds of other formats, and leverage all of FME’s data transformation and automation capabilities. For example, you can instantly import SpatiaLite data into Google Maps Engine using our free Data Loader for Google Maps Engine.

FME reads and writes a variety of open source databases.

3. PostGIS

PostGIS is a spatial database that adds support for geographic objects and location queries to PostgreSQL. FME’s PostGIS Reader / Writer lets users integrate hundreds of data sources with this format. Watch Paul Ramsey’s FME UC talk to see the evolution of PostGIS, from the ideas that inspired it to its widespread use today.

4. JTS and GEOS

JTS and GEOS (Geometry Engine – Open Source) provide spatial predicates and functions for processing 2D geometry. JTS is the Java library and GEOS is the C++ library. Some of FME’s powerful geometry transformations are based on GEOS/JTS algorithms.

5. OGR and GDAL (Geospatial Data Abstraction Library)

These OSGeo libraries support reading/writing over 50 raster formats (GDAL) and 20 vector formats (OGR). FME uses these libraries to add several readers and writers to its list of supported formats, which means these formats gain a wide range of enterprise transformation and automation capabilities.

Bonus: if you use a GDAL-based format in FME, you can feel comfortable knowing it was probably implemented by our in-house world Tetris champion.

6. FDO

FDO works with a variety of geospatial data. This OSGeo API brings additional formats to FME, for example SQLite. Safe was one of the earliest adopters of this API (version 3.0) and is acknowledged as an official Product Using FDO.

7. Ingres

Ingres is an RDBMS that supports large commercial and government applications. Safe’s partnership with Actian resulted in an open-source FME reader/writer for Ingres tables. This means increased data accessibility for Ingres users, making it easy to integrate spatial and enterprise data.

FME Workbench and the FME Data Inspector are available on Linux.

8. Qt

Qt is an application framework that we’ve used to help make FME fully cross-platform. Since FME 2013, FME has been available in beta on Mac and Linux platforms.

9. Interlis

Interlis is a geodata modeling and integration language adopted by the Swiss government as their national standard. Eisenhut Informatik is one of Safe’s longest standing open source partners, and their ili2fme plug-in allows Interlis data to be translated to/from any of the formats supported by FME.

10. LASzip

LASzip is a specialized library by Martin Isenburg that compresses LiDAR data without information loss—turning chubby LAS point clouds into lean, manageable LAZ files. The incorporation of this technology into FME has resulted a great improvement in the ability to archive and exchange point cloud data.

But Wait, There’s More
